This application is a divisional application divided out of myco-pending patent application Ser. No. 285,098 filed on April 30, 1952,for a Lounge Chair.

The invention relates to articles of furniture and more particularly tofoldable lounge chairs.

An object of the present invention is to provide a foldable lounge chairwith a link system including a movable back-rest and a movable sittingstructure which may be readily and conveniently brought into differentpositions, when the lounge chair is set up.

Another object of the present invention is to provide a lounge chairhaving a back-rest and a sitting structure included in a link system,which lounge chair may be readily collapsed and set up.

Another object of the invention is to improve on the construction offoldable lounge chairs as now customarily made.

Other objects and structural details of the invention will be apparentfrom the following description when read in conjunction with theaccompanying drawings forming part of this specification, wherein:

Fig. 1 is a side elevational view of a foldable lounge chair accordingto the invention, and

Fig. 2 is a side elevational view of the lounge chair shown in Fig. 1,wherein, however, the lounge chair is in collapsed condition.

Referring now to Figs. 1 and 2, I I generally indicates a support madeof tubular material. Said support H0 comprises a rear portion I09 and afront portion III hinged to each other at I44. The side frames of therear portion I09 are connected with each other by a cross-bar H2. Theside frames of the front portion III of the support H0 are connectedwith each other by a cross-bar H3 which may be integral with the sideframes. On each side of the chair one end of an arm I46 is swingablymounted at I48 on a lug I50 rigidly connected with the cross-bar II3 ofthe front portion III of the support I I0. When the lounge chair is setup, as shown in Fig. 1, said swingable arm I46 abuts against saidcross-bar I I3 whereby it is held in a fixed position.

A disk-like controlling member I26 is swingably mounted on the other endof the arm I46 at I28.

The back-rest I I4 is pivoted to the rear portion I09 of the support H0at H6. The rear end portion of the sitting structure I I8 including theseat I20 and the leg-rest I22 as a unit is pivoted to the back-rest H4at I24.

and this application March A controllin link I32 is pivoted at one ofits ends to the controlling member I26 at I34 and at its other end tothe sitting structure H8 at I36.

One end of a guiding link I38 is pivoted to the controlling member I26at I40, the other end of said guiding link I38 is pivoted at I 42 to abracket I47 rigidly connected with the seat portion I23 of the sittingstructure H8.

The three pivotal connections I28, I34 and I40 of the controlling memberI26 are spaced from each other.

When the lounge chair is set up, as shown in Fig. 1, the movable membersof the lounge chair may be readily brought from the sitting position,shown in full lines, into the reclined position, shown in dash and dotlines, and vice versa.

When it is desired to collapse the foldable lounge chair, it may begripped at the leg-rest I22, whereupon the sitting structure I I8 may beswung about the pivot I24, whereby the front portion III of the supportH0 is swung about the pivot I44 while the arm I46 swings about the pivotI48 so that finally the elements of the chair assume the position shownin Fig. 2.

I have described a preferred embodiment of my invention, but it isunderstood that this disclosure is for the purpose of illustration, andthat various omissions and changes in shape, proportion and arrangementof parts, as well as the substitution of equivalent elements for thearrangements shown and described may be made without departing from thespirit and scope of the invention as set forth in the appended claims.

For example, stopping means may be arranged on the chair for limitingthe end positions of the movable members of the chair, i. e. the sittingposition and the extreme reclined position.

Furthermore, locking means could be arranged on the chair for holdingthe movable members of the chair in any desired position.

What I claim is:

1. A foldable lounge chair, comprising in combination: a support, saidsupport including a rear portion and a front portion pivotally connectedwith each other and an arm swingably mounted on said front portion at apoint spaced from the pivotal connection between said rear and frontportions of the support, holding means on the front end portion of saidsupport for cooperation with said arm so as to hold same in a fixedposition when the lounge chair is set up, aback-rest pivoted to saidrear portion of the support, a sitting structure including a. seat and aleg-rest rigid with each other, the rear end portion of said sittingstructure being pivoted tosaid backrest, a controlling member pivotallyconnected with said swingable arm of the support, a controlling linkpivoted at one of its ends to said controlling gnembeinat a pointspaced.from the pivotal CODIlGCtlOiT of: the. latten with. said: swing ablearm, the other end of said controlling link being pivoted to the frontportion of said sitting structure and a guiding link pivoted at one ofits ends to said controlling member at a point'spa-ced-ilm from thepivotal connection of the latter. with.
